1 Distance and position guidelines
These guidelines are recommendations only and it is important that you refer
to your appropriate governing standards at all times.
When positioning your ZetaBeam there are important factors that you should consider, mainly what
distance you are covering and the optimal position in the building.
What distance?
The standard ZetaBeam is suitable for distances of 5m to 40m to the reflector. If you require 40m to
80m you will need to use the mid range reflector extension kit. For ranges of 80m to 100m you will
require the long range reflector extension kit.
5 to 40 metres the standard zetabeam
The standard ZetaBeam comes boxed with the head unit, low level controller, one reflector, 3mm allen
key and quick start installation guide, this should be used for distances over 5m and up to 40m.
Standard ZetaBeam covers 5m and up to 40m
40 to 80 metres - the standard zetabeam + mid range 40 to 80m kit
For distances of 40 to 80 metres you will need to use the standard
ZetaBeam and a mid range extension kit (the mid range kit comes
with a backing plate and 3 extra reflectors, you will need to add the
reflector from the standard kit to the mid range kit with the screws
provided).
80 to 100 metres - the standard zetabeam + long
range 80 to 100m kit
For distances of 80 to 100 metres you will need to use the standard
ZetaBeam and a long range extension kit (the long range kit
comes with a backing plate and 8 extra reflectors, you will need to
add the reflector from the standard kit to the long range kit with
the screws provided).
What position?
A roof is considered flat unless the height of the apex is greater then 0.6m. If the roof is flat the
ZetaBeam system can be placed anywhere under the roof between 0.3m and 0.6m below the roof, up to
a maximum height of 40m from the floor. The ZetaBeam has a detection area of 7.5m either side of the
beam. If the roof is considered to have an apex, place the ZetaBeam system 0.3m to 0.6m down from
the top of the apex, up to a maximum height of 40m from the floor. The maximum protected area either
side of the beam can be extended by 1% for every degree of roof pitch, see the example below:
0.3m - 0.6m

You should always position the beam at least 0.5m away from any protrusion
Note. Careful design consideration should be made when positioning beams and reflectors in
environments that can be susceptible to condensation i.e. warehouses near to water that have areas
open to the outside environment or that are exposed to quick extreme changes in temperature. To assist
with this problem that can affect all beam detectors we produce an anti-fog kit comprising of a specially
coated reflector and lens cover. Individual reflectors are also available. The standard ZetaBeam and
range kits can be supplied as anti-fog sets as a special order.
2 Installing, commissioning and testing
step 1 mounting the head
Screw the head backing plate to the wall - always try to use as sturdy a location as possible, such
as brick or major structural steels (avoid mounting to outer metal cladding etc). Avoid mounting the
head where direct sunlight can shine directly into the ‘eyes’ of the beam (care should be taken when
mounting in glass atriums). Ambient sunlight will not affect the beam.
Also available - unistrut adapter plate
Use this accessory for easy mounting to unistrut fabrication. Holes are predrilled to the correct pitch of the head and conveniently positioned for use
with unistrut.

Generic wiring configurations
the zetabeam is a conventional device, below are suggested wiring configurations for single and multi
heads on a zone. the zetabeam can easily be made addressable with the use of a manufacturers
interface and in some cases can also be powered from the loop, ie with the Apollo XP95 switch monitor
with isolator. Most wiring diagrams can be found on our website in more detail and in PDF format, go to

step 3 commissioning
Commissioning the ZetaBeam is a simple procedure outlined in the following step by step explanation.

is if you need to change this use the right and left
hand keys to scroll through languages, when you have found your language press enter or if you are
happy with English press the down key to continue. If you have changed the language the system will
continue in your chosen language.
5. Press enter and you will now see the commissioning speed screen. In most cases it is recommended
to use fast mode (in normal mode the system uses 3.5mA, in fast mode it uses 17mA) - if you are
commissioning more than one beam at a time and the system cannot support the extra draw it may
be necessary to use normal mode to prevent excessive current draw. Fast mode allows x4 times
faster motor response and it may be quicker to commission each beam in turn. Once commissioning is
complete the ZetaBeam will automatically revert to normal low power mode - (3.5mA).
6. Use the left and right keys to toggle between fast and normal, the * indicates which mode is
selected. Press the enter key to continue.

stage two, pre-alignment
7. The next screen is
pre-alignment
this is probably the most important part of setting up your
beam. Pre-alignment sets up the amount of power you need for the distance you are covering and
can indicate if you are receiving unwanted reflections from anything else in the beam path.
8. Press enter to begin pre-alignment. Remember no reflector. You will see the screen below. Take a
moment to understand what the figures on the screen mean.

‘Y’ -vertical lense position in degrees
X+0.00°
5%
received signal strength
0% P
Y+0.00°
‘P’ indicates pre-alignment
Receiver sensitivity starts off at 5% and output power starts at 10%. The beam will start by raising its
sensitivity first and can rise all the way up to 100%, after this the output power will rise. The objective of
pre-alignment is to adjust the output power to the correct levels for the distance to be covered. As there
is no reflector we are looking for a reflection off the far wall. Power levels will rise until they reach a
maximum of anything up to 6 to 7% of received signal strength (nb. figures may fluctuate between these
values), once this is achieved the power level will automatically stop rising any further.
By looking at the table below you need to judge if you are receiving enough power to cover the required
distance.
5m.........5%
30m......20%
60m......40%
90m......65%

40m......25%

Note. Anything more than these levels is good and continue down to 9. If you are receiving noticeably
less read on below.
These figures are approximate but if you are receiving noticeably less than these figures you may be
receiving a reflection from an object nearby and not the far wall. By moving the beam (looking at the far
wall) left (x-) right (x+) up (y+) and down (y-) you can move the beam path away from the obstacle. By
doing this you will be able to achieve a suitable output power. In extreme cases it may be necessary to
physically move the beam head to obtain a clear line of sight.

these settings by pressing the right key.
Note. It may be that no reflection is received and power and sensitivity levels rise to their maximum, if
this is the case pre-alignment will automatically register Pre-Align - Complete. Confirm these settings by
pressing the right key.

stage three, manual alignment
You will now see the manual alignment screen showing anything between 0 and 6%. This is the amount of
received signal with no reflector that the beam is picking up from the environment.
10.NOW place or uncover the reflector on the blank wall directly opposite the beam head ensuring there
is a clear path through any obstructions such as structural steels etc.
It is important that there is a clear line of sight between the reflector and beam head. The beam must
see at least 200mm of clear space around the reflector to enable the beam to see the edges of the
reflector to allow successful auto alignment in the following stage.
200mm of clear space from
the edges of the reflector
Once the reflector is in place and visible there should be a big jump in the received signal (AQ). This
means that the head is seeing and receiving a signal back from the reflector. In most cases this will result
in a received signal of over 100%.

As long as there is a received signal of over 40% you can move onto the next stage: Auto Alignment,
No.11.If the AQ reading is below 40% it means the head is not seeing the reflector and will abort Auto
Alignment. The next stage is to manually move the beam to achieve an AQ reading of over 40%, ideally
over 100%. The higher the AQ the quicker it will auto align. This is done by manually moving the x and y
motors to obtain a received signal from the reflector.
In the example below we can see that the reflector is below the eye line of the beam head, so in this
case you would need to lower the angle of the beam (-Y) until you receive an AQ of over 40%.

First you will see the sensitivity and power readings drop if the received signal is over 100%. Once at
100% or if the reading is under 100% the ZetaBeam will automatically move its y and x axis until it
centres itself onto the middle of the reflector. It does this by seeing highs and lows as it falls on and off
the reflector (seeing the edges of the reflector) once it has found all the edges it will then calculate and
move to the centre of the reflector.

Auto alignment in ‘fast’ mode will take, on average, 3 minutes and in normal mode up to 30 minutes the
better the beam is aligned before auto alignment (high AQ readings) the shorter the align time. Once
finished Align Complete will appear on the screen, simply press left back to OK and exit.
You will now see this screen AQ may fluctuate a couple of % above and below 100%
Air Quality 100%
Status - NORMAL
Now proceed to step 4 - testing - the final stage of commissioning.
step 4 testing
1. Fault test This is done to confirm that the returned signal is from the reflector. Cover the entire
reflector within one second. If the beam is correctly targeted onto the reflector the AQ will
drop to 0% (max 10%) and will fall into a ‘fault’ condition (after 10 seconds). Amber LEDs
will flash on both the controller and the beam head, the word FAULT will appear on the
display. If the AQ is still above 10% reflections are also being returned from something else
other than the reflector. This should be rectified and a fault test performed again until AQ
drops below 10%.
2. Fire test Having completed the fault test the fire test confirms the functionality of
the beam. Having just covered the reflector completely for the fault test now let the
beam recover to its normal state and then cover half the reflector, in effect restricting the
returned signal to 50%, the beam should then fall into a ‘fire’ condition (after 10 seconds).
Once you have successfully completed both tests your ZetaBeam is
commissioned.
You can now fine tune your beam to suit the environment if needed. Look through the following menus to
see adjustments that can be made.

be quicker to commission each beam in turn. Once commissioning is complete the
ZetaBeam will automatically revert to normal low power mode - (3.5mA).
Press enter enter to start pre-alignment. In pre-alignment you should ALWAYS
COVER THE
REFLECTOR. Starting at 10% power and 10% receiver sensitivity,
the receiver sensitivity will automatically increase to a maximum of 100% then the
output power will increase. These settings will automatically stop when a received
signal strength reaches 6% - this received signal is the returned strength of the output
signal without a reflector (if no return signal is received the beam will reach full
power and the screen will say Pre-Align - complete). If you don’t receive high enough
output power and receiver sensitivity readings this will usually be because you are
receiving a reflection from an object nearby - use the left, right, up and down keys

the fire relay. This sensitivity can be adjusted between 25% (sensitive) and 50% (less
sensitive) (press enter to return to mode change or down to go to time to fire).
Time to fire. Here we can adjust how long the beam has to be in fire before the fire
relay is triggered. This is factory set at 10s, you may want to increase this if there is
something that may momentarily obscure the beam path (birds / forklift truck) this
can be adjusted between 2 and 30 seconds by using the right and left keys (press
enter to return to mode change or down to go to time to fault).
Time to fault. Here we can adjust the time to fault between 2 and 60 seconds
(factory set at 10 seconds). For a beam to go into fault the beam path must be totally
blocked within ONE second. By using the right and left keys (press enter to return to
mode change or down to go to auto reset).
Auto reset. The beam is factory set to auto reset when the received signal raises
above the fire threshold hysteresis. This can be set to latching if your system requires
this. Change by using the right and left keys (press enter to return to mode change or
down to go to align on / off).
Align on / off. You may want to turn the auto alignment function off, for example,
in an environment that often gets filled with welding smoke, the auto align function
kicks in when the received signal drops below 90%, the point that the beam
automatically checks for building movement. The beam will try to align through the
smoke which could be a problem if it is unable to see the edges of the reflector. Use
the right and left keys to turn off and on. When turning this function off extra care
should be taken to ensure that the beam head is on a sturdy fixing ie., brick wall or
major structural steel. Auto alignment will still function in commissioning (press enter
to return to mode change or down to go to align time).
Align time. This is factory set to 4hrs, you can adjust this, by using the right and left

identifying the beam head you are working with (press enter to return to mode
change or down to go to phase).
Phase. When using multiple beams that face each other the beam output signals could
phase together and can cause unreliable readings, by setting each beam to phase
differently alleviates this problem. Use the right and left keys to give each beam a
different phase pattern (length between output beam sample times) you can choose
between 0 (default setting) and 6 (press enter to return to mode change or down to
go to hysteresis).
Hysteresis. Changing the hysteresis will change the delay in returning from a fire state
back to a normal state, for example, the beam is factory set at 15% so if the beam
falls into fire at 65% (35% threshold) it has to recover 15% to 80% before it returns
to normal. This action prevents small fluctuations in returned signal causing the
beam to fall in and out of a fire state. This can be adjusted between 1% and 40% by
using the right and left keys (press enter to return to mode change or down to go to
compensation fire / fault).

Dirt Comp
Dirt Comp. This screen shows how much the beam has compensated for dust buildup on the beam head and reflectors, ALWAYS take a note of this value as part of your
routine maintenance to see any build-up pattern, if you see figures above +50% you
should clean both the lens face and the reflectors (once cleaned you should instigate
an auto alignment to re-calibrate the beams settings).
It is possible that you may see a negative number here, this can happen when the
ZetaBeam has been commissioned in a ‘dirty’ atmosphere such as builders dust which,
once cleared, the beam then compensates for. To reset, perform an auto alignment to
re-calibrate the beam (press enter to return to beam maintenance or down to go to
